Answer
(d) Oviduct.
The operation is a TUBECTOMY, in which the OVIDUCTS (fallopian tubes) are cut and tied. The ovum can then no longer travel down the tube and sperms cannot reach it, so fertilisation is impossible.
The three wrong options all belong to the URINARY system (ureter, urethra) or are the wrong reproductive organ (uterus) — and note that the uterus is not cut in a tubectomy at all.
THE MALE EQUIVALENT is VASECTOMY, in which the VAS DEFERENS is cut and tied. Each name contains its structure: TUBE-ctomy and VAS-ectomy.
WHAT THE OPERATION DOES NOT DO: a tubectomy does not stop ovulation, menstruation or hormone secretion. Only the passage of the gametes is blocked.
